Zirconia Toughened Alumina Description
Zirconia toughened alumina (ZTA) ceramics yog cov ntaub ntawv cog lus zoo heev rau kev siv cov qauv thiab biomedical vim lawv cov hardness siab, tawg toughness, lub zog, corrosion thiab abrasion kuj thiab biocompatibility zoo heev.
Zirconia toughened alumina yog tsim los siv kev ntxhov siab vim kev hloov pauv ntawm cov nplua tetragonal zirconia hais. Qhov loj me me me thiab kev faib tawm no ua rau muaj zog heev, toughness thiab tsis kam rau thermal shock; cov khoom uas ua rau ZTA haum rau ntau yam kev siv thiab ib puag ncig.
Feem ntau, zirconia toughened alumina yuav muaj zirconia cov ntsiab lus ntawm 10 feem pua -20 feem pua. Raws li qhov feem pua ntawm cov ntsiab lus no, cov khoom ntawm ceramic tuaj yeem hloov kho kom haum rau daim ntawv thov hauv nqe lus nug. ZTA feem ntau suav hais tias yog ib qho nruab nrab ntawm alumina thiab zirconia thiab yog raws li tus nqi, feem ntau ua zirconia toughened alumina tus nqi siab, nqi zoo.
Zirconia-toughened aluminas can be regarded as a new generation of toughened ceramics; for example, a toughness of >12 MPa m0.5 tau txais, piv nrog 3 MPa m0.5 rau kev lag luam alumina ceramics. Lub zog tawg ntawm ZTA kuj tseem zoo heev ntawm qhov ntawd rau alumina. Cov khoom siv kho tshuab ntawm ZTA tseem ceeb heev nyob ntawm lawv cov microstructures, uas tuaj yeem tsim los ntawm cov kev siv tshwj xeeb thiab tswj los ntawm kev npaj hmoov thiab cov txheej txheem densification.
